The cache data saving unit 18 saves the cache.

Details of Process

In the following, a description is given of details of processes of the information processing system 1 according to the present embodiment.

Login Process

FIG. 4 is a sequence diagram of an example expressing login processing procedures of the information processing system 1 according to the present embodiment. In step S1, the user activates the application installed in the client device 20. Note that the application may be an application exclusive to the storage server 10A, or a general-purpose application such as a web browser. The user inputs information (user identification information) necessary for login such as a login ID and a password, according to need.

In step S2, the client device 20 requests login to the storage server 10A. In step S3, the storage server 10A executes a login process from the client device 20. When the login from the client device 20 is successful, in step S4, the storage server 10A requests a login process to the cloud storage 30 associated with the user who has logged in.

Furthermore, when the login to the cloud storage 30 is successful, in step S5, the storage server 10A acquires index information from the cloud storage 30. In step S6, the storage server 10A updates the index information saved in the index information saving unit 15 with the use of the acquired index information.

Furthermore, FIG. 5 is a flowchart of an example expressing login processing procedures of the storage server 10A according to the present embodiment. In step S11, the storage server 10A receives a login request from the client device 20. The login request includes, for example, a login ID and a password as user identification information.

In step S12, based on the login request from the client device 20, the storage server 10A performs an authentication process with the use of the login ID and the password received at the time of the login request and authentication information as illustrated in FIG. 6 saved in the authentication information saving unit 14.

FIG. 6 is a configuration diagram of an example of authentication information. The authentication information illustrated in FIG. 6 includes the authentication information of the storage server 10A and the authentication information of the cloud storage 30. The authentication information of the storage server 10A is authentication information used for the client device 20 to log into the storage server 10A. Furthermore, the authentication information of the cloud storage 30 is authentication information used for the storage server 10A to log into the cloud storage 30.

As the authentication information of the storage server 10A, information of the device such as a device ID may be used, other than the login ID and the password. By associating the information of the device with the login ID and the password, the information of the device may be used as user identification information.

Furthermore, the authentication information of the cloud storage 30 is associated with the authentication information of the storage server 10A. In the authentication information of FIG. 6 , authentication information of one or more cloud storages 30 is associated with authentication information of a single storage server 10A. The authentication information of the cloud storage 30 includes a cloud name, a login ID, and a password.

When the login from the client device 20 is successful, in step S13, the storage server 10A acquires, from the authentication information of FIG. 6 , the authentication information of the cloud storage 30 associated with the authentication information of the storage server 10A of the user who has logged in.

In step S14, when the storage server 10A successfully acquires the authentication information of the cloud storage 30, the storage server 10A performs the processes of step S15 and onward. In step S15, the storage server 10A uses the acquired authentication information of the cloud storage 30 to request a login process to the cloud storage 30. When the login to the cloud storage 30 is successful, in step S16, the storage server 10A acquires index information from the cloud storage 30. In step S17, the storage server 10A uses the acquired index information to update the index information saved in the index information saving unit 15.

For example, the storage server 10A to which a “user A” has logged in acquires, from the authentication information of FIG. 6 , the authentication information of the cloud storages 30 whose cloud names are “cloud storage A” and “cloud storage B”. To the cloud storage 30A having a cloud name “cloud storage A”, the storage server 10A makes a login request with a login ID “user 01” and a password. Furthermore, to the cloud storage 30B having a cloud name “cloud storage B”, the storage server 10A makes a login request with a login ID “user 001” and a password.

FIG. 7 is a configuration diagram of an example of index information. The index information of FIG. 7 includes attribute information such as a cloud name, a file path, full text information, the update date, permission, the owner, the group, and the file size.

Full text information is text information of a document file, when the target file is a document file. Permission is information relevant to the access rights to a file. Permission is described as, for example, “-rw-r--r--”, where the first character is information for identifying the type of the target data, such as a file and a directory. The next three characters indicate the access rights of the owner. Among the three characters, the first character “r” indicates reading of the target data (read), the second character “w” indicates writing of the target data (write), and the third character “x” indicates execution of the target data. When the owner cannot execute the respective processes, the position of the target character is indicated by “-”. The next three characters, which follow the three characters indicating the access rights of the owner, indicate the access rights of the group of the target data. The three characters, which follow the three characters indicating the access rights of the group, indicate the access rights of another user. Note that the contents indicated by the three characters of the group and another user, are the same as the three characters of the access rights of the owner.

For example, in the case of “-rw-r--r--”, the access rights are interpreted as follows. “The target data is a file, the owner can read and right, but cannot execute. The user of the group can read, but cannot write or execute. Another user can read, but cannot write or execute.

Referring back to FIG. 7 , the owner and the group indicate the owner and the group described with respect to the permission.

The storage server 10A saves, in advance, the index information for searching as illustrated in FIG. 7 , in order to search for a file saved in one or more cloud storages 30 in a cross-sectoral manner. In order to create the index information, the storage server 10A periodically accesses the cloud storage 30 to scan whether there is a file, and updates the attribute information.

When the storage server 10A cannot access the cloud storage 30, in order to increase the search speed, the index information of a file saved in a cloud storage 30 that cannot be accessed, is deleted. In the searching by the storage server 10A, it is possible to specify search refinement and the search order, based on the type of attribute information of the index information.

For example, in the index information of FIG. 7 , when the search range is refined to a cloud name “Cloud A”, the range of the search by the storage server 10A is refined to files saved in the cloud storage 30A having a cloud name “Cloud A”. Furthermore, according to the specification of the search range, the search may be performed in the order of the cloud storage 30A → the cloud storage 30B → the cloud storage 30C. Furthermore, the search may be performed from the newest to the oldest update date of the file.

Note that the index information of the cloud name “self-storage” in the index information in FIG. 7 is index information for searching for a file saved in the file data saving unit 17 of the storage server 10A.

Update Process of Index Information

The index information may be created and updated at the time of the login process and when registering the authentication information, and may be updated at regular intervals while the storage server 10A is being activated, as illustrated in FIG. 8 .

FIG. 8 is a sequence diagram of an example of processing procedures of updating index information performed by the information processing system 1 according to the present embodiment. In step S21, the user activates the storage server 10A. While the storage server 10A is being activated, steps S22 and S23 are repeated at regular intervals.

In step S22, the storage server 10A acquires index information form the cloud storage 30. In step S23, the storage server 10A updates the index information saved in the index information saving unit 15, with the use of the acquired index information.

Process of Displaying File List

FIG. 9 is a sequence diagram of an example of processing procedures of displaying a file list performed by the information processing system 1 according to the present embodiment. In step S31, the user operates the client device 20, and requests the display of a file list. In step S32, the client device 20 requests the storage server 10A to acquire the file list. In step S33, the storage server 10A performs a process of creating a file list. Note that details of the process of creating a file list are described below. In step S34, the storage server 10A sends the created file list to the client device 20. The client device 20 displays the received file list. The user can confirm the file list displayed by the client device 20.

FIG. 10 is a flowchart of an example of processing procedures of creating a file list performed by the storage server 10A according to the present embodiment. In step S41, the storage server 10A receives a request to acquire a file list from the client device 20.

Furthermore, in step S42, the storage server 10A refers to the index information saved in the index information saving unit 15, and searches for a file that a logged in user can access. Note that a file that a logged in user can access may be a file that only the logged in user can access, or a common file that all users can access. The determination of whether access is possible is made based on the permission associated with each data illustrated in FIG. 7 .

In step S43, the storage server 10A creates a list of files that are accessible by a logged in user, from the search result of step S42. Then, in step S44, the storage server 10A returns the file list created in step S43, to the client device 20.

The client device 20 that has received the file list displays the file list as illustrated in FIGS. 11A through 11D, for example. FIGS. 11A through 11D are image diagrams of examples of displayed file lists. In the examples of displayed file lists illustrated in FIGS. 11A through 11D, file A and file D are included in a cloud storage A. Furthermore, in the examples in FIGS. 11A through 11D, file C is included in a cloud storage B. Furthermore, in the examples in FIGS. 11A through 11D, file B and file E are included in a cloud storage C.

FIG. 11A illustrates a displayed file list displaying all of the files in parallel. Furthermore, FIG. 11B illustrates a displayed file list in which the files are divided into folders of each of the cloud storages 30 in which the files are saved.

Furthermore, FIG. 11C illustrates a displayed file list displaying all of the files in parallel, which are indicated in different colors according to the cloud storage 30 in which the file is saved. Furthermore, FIG. 11D illustrates a displayed file list displaying all of the files in parallel, which have different icons applied according to the cloud storage 30 in which the file is saved.

Note that when the same file is saved in a plurality of cloud storages 30, the file list may only display one file. It may be determined whether the files are the same file, based on whether the file name matches/does not match. Furthermore, it may be determined whether the files are the same file, based on whether the full-text information included in the index information matches/does not match. Furthermore, it may be determined whether the files are the same file, based on whether both the file name and the full-text information included in the index information match/do not match.

In a case where file A, file B, and file C are included in the “cloud storage A”, and file C, file D, and file E are included in the “cloud storage B”, the file list is displayed as illustrated in FIG. 11A.

Search Process

The storage server 10A, which has received a search request from the client device 20, executes a search process as illustrated in FIG. 12 . FIG. 12 is a flowchart of an example of search processing procedures of the storage server 10A according to the present embodiment.

In step S51, the storage server 10A receives a search request from the client device 20. In step S52, the storage server 10A determines the search condition of the received search request. The storage server 10A holds, as index information, various items of attribute information of files (of self-storage) saved in the file data saving unit 17 and files (of external storages) saved in the cloud storage 30.

Accordingly, in step S53, the storage server 10A can specify search refinement and the search order of the index information, based on the search condition. The storage server 10A searches the index information based on the search condition. In step S54, the storage server 10A consecutively returns the information of the files hit by the search, to the client device 20 that is the search request source. Furthermore, in step S55, the storage server 10A returns the number of hits of the search to the client device 20 that is the search request source.

Note that when the files hit by the search can be downloaded from the cloud storage 30, the storage server 10A may download the files from the cloud storage 30 in the order that they were hit by the search.

Uploading File

The user may upload a file from the client device 20 as illustrated in FIG. 13 . FIG. 13 is a sequence diagram of an example of upload processing procedures of the information processing system 1 according to the present embodiment. Note that FIG. 13 illustrates an upload process in which the upload destination is specified.

In step S61, the user operates the client device 20 and requests the display of the upload data selection screen. In step S62, the client device 20 creates a list of data that can be uploaded, and displays a screen as illustrated in FIG. 25 . In step S63, the user selects data to be uploaded, from the displayed data list. For example, as illustrated in FIG. 26 , it is assumed that a user has selected “file A”, “file C”, and “file E” from the list, and has selected “complete”. Furthermore, the user selects the self-storage or the cloud storage 30, as the upload destination of the data. In step S64, the user requests the client device 20 to execute the uploading. For example, as illustrated in FIG. 27 , a list of upload destinations (including self-storage and cloud storage) is displayed on the client device 20, and the user selects the upload destination and selects “upload”. Note that at this time, the user may select a plurality of upload destinations.

In step S65, the client device 20 requests the storage server 10A to upload the data, based on the upload execution request from the user. This execution request includes information (for example, identification information for identifying the upload destination) relevant to the upload destination to which the data is to be uploaded. In step S66, the storage server 10A checks the upload destination.

When the upload destination is the self-storage, in step S67, the storage server 10A saves the data selected by the user in the upload destination selected by the user. Furthermore, when the upload destination is the cloud storage 30, in step S68, the storage server 10A requests the cloud storage 30 that is the upload destination to upload the data selected by the user. In step S69, the cloud storage 30 saves the uploaded data.

Note that after the uploading of the data is completed, the storage server 10A can update the index information of the file saved in the cloud storage 30 that is the upload destination. As described above, the storage server 10A can also update the index information at the timing of uploading the file.
